
If you would like to connect to the "RESET" and "LS IN" terminal please use a non-contact
voltage switch. Example, LS torque wrench, relay, etc.

Do not feed the external power to input circuit to prevent damage.

Set the load of the contact output within the rated load. Relay output rating: DC30V 1A, AC125V
0.5A. The above rated contact capacity is according to resistance load. Some kinds of loads have a
big difference between the steady-state current and the inrush current. Typical loads and inrush
currents are as follows:
Kind of Load Inrush Current
Resistive Load 1 time as large as the steady-state current
Solenoid Load 10 to 20 times as large as the steady-state current
Motor Load 5 to 10 times as large as the steady-state current
Incahdescent Lamp
10 to 15 times as large as the steady-state current
Mecury Vapor Lamp
About 3 times as large as the steady-state current
Sodium Vapor Lamp
1 to 3 times as large as the steady-state current
Capacitor Load 20 to 40 times as large as the steady-state current
Trans Load 5 to 15 times as large as the steady-state current
